Break-In Recommendations - KYMCO DOWNTOWN 300i 2011 Owner's Manual

BREAK-IN RECOMMENDATIONS

Break-in recommendations
The first 600 miles (1,000 km) of riding are the most important in the life of your scooter. Proper break-in operation during this time will help ensure
maximum life and performance from your new scooter. Proper break-in operation allows the machined surfaces to polish each other and mate
smoothly.
Your scooter's reliability and performance depend on special care and restraint exercised during the break-in period. It is especially important that
you avoid operating the engine in a manner which could expose the engine parts to excessive heat. The following guidelines should be followed
during the break-in period:
Maximum throttle operation:
Vary the engine speed: The engine speed should be varied and not held at a constant rate for long periods of time. This allows the parts to be
"loaded" with pressure, and then unloaded, allowing the parts to cool. This aids in the mating process of the engine and transmission components.
It is essential that some stress be placed on these components during break-in to ensure this mating process. Do not, however, apply excessive
load on the scooter's drive line.
Avoid constant low speed: Operating the engine at constant low speed (light load) can cause parts to glaze and not seat in properly. Allow the
engine to accelerate freely through the gears, without exceeding the recommended throttle openings. Avoid using full throttle for the first 500
km (300 miles).
The initial service: Observe your first and most critical service. The 300km (200 mile) initial service is the most important service your scooter will
receive. During the break-in period all of the engine components will have worn in and all of the other parts will have seated in, so adjustments will
be required. All fasteners will be tightened, and the contaminated engine oil will be replaced.
NOTE: Completion of the 300km (200 mile) initial service will ensure optimum service life and performance from your scooter. Do not
delay in having this service performed once your scooter reaches this mileage.
The 200 mile (300 km) service should be performed as outlined in the maintenance
schedule section of this owner's manual. Pay particular attention to the cautions and
warnings in the maintenance schedule section. Unless you have formal training as a
service technician and have access to KYMCO technical reference materials, it is strongly
suggested that you have the initial service performed by a KYMCO dealer.
Initial 600km (300 miles): ............... Less than 1/2 throttle
Up to 1000km (600 miles): ............ Less than 3/4 throttle
